I agree with @gfron1 that some of the "celeb-judges" don't always add that much, although some have made some interesting observations and Hasan Minhaj added some levity to the discussions. I wondered what sort of weighting the critic's opinion was given when it came to the final decisions. At least that judging panel doesn't actually eliminate anyone.
Edited to add this clip from the Indian episode of The Final Table for the non-Netflix peeps. This shows the judging of one team by the 2 celeb-judges and a food critic from India.
